Te rill-whom 'itma/y'conccm:

Be it known that I, THOMAS G. PLANT, a citizen of the United'stateaand a resident ofBoston, in the county of Suffolk and State of Massachusetts, have invented an, Improvement in Boot and Shoe Bufin Machines, of which-the following descrlption, incon'nection with the accompanying drawings, is a specification, like numerals on the drawings-representing like parts.

The-invention to be hereinafter described relates to bu'fing machines for acting upon and finishingboots and shoes.

As'well understood by those skilled in the art the bufling-rolls have'been usually covered by an abrading material for acting upon the sole portion of boots and shoes, and a hood has been employed for carrying away the dust and other particles detached from the shoe. Where the rolls have been disposed upon a supporting frame one above the other, some of the material detached from the shoe by the upper roll has been thrown downward away from themouth of the dust trunk, and such material would either accumulate on and about the machine frame or-fall onto the lower roll, thus introduci objections well understood by those skille in the art.

The aims and purposes of'the present in vention are to providea bufiing machine of simple construction wherein the material detaehed from the shoe will be effioiently carried into the dust trunk, all as will be hereinafter more fully described in connection with the accompanying drawings which illustrate one'form of means f0 carrying the invention into effect.

In the drawings: Figure 1 is a front elevation, with parts broken away, of a bufiing machine embodying features of the present 1 invention; and Fig. 2 is a section on the line 22 of Fig. 1.

The machine frame may be of any'usual and desired character suitable to support the-operating parts and their associated ele-' ments, and 1n the present form of the invention consists of suitablejuprights' 1 connected-by cross ties 2, said uprights I having bearings 3 for a buffing shaft 4 on which may be mounted the roughing and finishing rolls 5 and 6. y

Below the bufing rolls 5 and 6 may be disposed another (pair of roughing and finishmg rolls 7 an -8,.said'rolls 7 "and '8 being Specification of Letters Patent. ahpp lication :filed October 19, 1909.

suitably mounted on a shaft 9,.one end of which finds a bearing in the upright -1 of the machine frame and the other end of which is mounted in a bearing 10 on a stand 11 extending upward-from the cross ties 2.

It will be noted in Fig. 1 that therolls 5 and 6, and the rolls 7 and 8 are preferably separated a short distance and that the rolls 5 and 6 may be preferably disposed above the rolls 7 and 8, the rolls 7 and 8 being preferably extended laterally to one side of the rolls 5 and 6, that is, the rolls 7 and 8 are not in the same vertical zone, nor are they of the same length, as clearly made apparent by Fig. '1.

The shafts 4 and 9 are extended to one side of the supporting frame and provided with the pulleys 12 and 13, respectively, over portion of a dust trunk 17, the mouth of which embraces the upper rolls 5 and 6 and has jointed thereto at 1-8 the cover 19 adapted when in operativeposition, as indicated in Figs. land 2, to extend over-the upper portion of the buffing rolls 5 and 6.

The dust trunk 17 extends downward and backward of the machine frame, as indicated in Figs. 1 and 2, and may be connected to any suitable source of power for creating a suction draft in the direction of the arrows, the construction being such that a shoe held, as in Fig. 2, against one of the upper rolls may be properly treated thereby and the particles detached therefrom be drawn more or less effectively into the dust trunk 17 Suitably mounted upon the machine frame is the lower dust trunk 20 which at its lower portion joins the lower portion of the dust trunk '17, as indicated at 21, the said two dust trunksthus leading to a single suction creating means.

The lower dust trunk 20 has its mouth shaped to partially embrace the two builing rolls7 and 8, so that the particles detached fromthe shoe by said rolls may be drawn. thereinto by the suction currents.

- are liable to be thrown downward and consethe lower dust trunk has pivoted thereto atquently not get into the mouth of the dust trunk 17. To meet this condition the present invention contemplates means for intercepting these downwardly directed particles and causing them to be passed into the dust trunk at a point below the mouth thereof. As one form of convenient means to this end 22 a cover plate 23 extending partially over the top of the lowerbufiing rolls, as ind1- cated in Figs. 1 and 2. Extending backward from the cover 23 is the deflector 2 1, the end 25 of which is adapted to contact with a stop 26 when the cover 23 is in its operative position covering the lower rolls.-

The wall 27 of the dust trunk 17 has a series of openings 28 disposed below the mouth thereof toward which the deflector extends,

"the construction being such that particles thrown from the shoe and failing to enter the mouth of the dust trunk 17 will be received upon the deflector 24' and directed thereby into the openings 28 of the dust trunk 17 under the influence of the ingoing currents of air, as indicated by the arrows, Fig. 1. I

From the described construction as one embodiment of the invention it will be noted that the bufiing rolls, while arranged one above the other, are notadisposed in the same Vertical zone, nor are they of the same length, the upper rolls 5 and 6 being of a combined length greater than that of the lower rolls. In view of this fact the deflector 24:, as indicated in Fig. 1, is carried laterally, as at 29, so that a portion of said defiector will extend under all portions of the upper bufiing rolls and consequently all material falling on such deflector or from the upper rolls may be directed into the dust trunk 17 In the described form of the invention the deflector 24; is made part of the cover 23 for the lower rolls, but obviously the invention is not limited in this respect, as the deflector and cover may be otherwise formed, and it will be understood of course that a similar deflector may be disposed below the lower roll if found desirable, but as such construction would be substantially identical with that illustrated by the deflector 24:, further elucidation thereof seems unnecessary.

It will also be apparent that changes and variations may be made in the form and disposition of the bufiin rolls with respect to each other, and that t ey may be supported otherwise than as shown within the true see c of the present invention.
